WALTER G. STANDING, OF SHARPSBURG, PENNSYLVANIA.

CHILL FOR SASH-WEIGHTS.

To all whom it may concern:

Be it known that I, WTALTER G. STANDING, a citizen of the United States, residing at Sharpsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im irovernents in Chills for SashVeights and do declare the following to be a iull, clear, and exact description of the invention, suoli as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures oi reference marked thereon, which form a part of this specification.

My invention relates to certain new and useiul improvements in chills for casting sash weights and consists of the construction and arrangement of parts shown in the accompanying drawings and described in the following specilication.

I am aware that patents have been issued for devices of a similar nature, reference being had more particularly to the patent issued January 1st. 1895 to George Buchanan, No. 531,774, whichsaid invention consists of a two part chill having an eye aperture eX- tending transversely through the same from side to side.

My improved chill is in three parts, and aims to overcome certain defects in the said patent above referred to, more particularly to the means I employ in keeping the two halves of the chill from separating when they are in their seat in the flask, thereby avoiding the possibility of forming a blind eye in the sash weight.

Another improved feature I include in my invention is a locking means whereby the two halves of the chill will be prevented from any longitudinal movement, one against the other,when seated in the iiask, thereby overcoming any possibility of the flask bleeding, and destroying the entire cast of metal.

Figure 1 shows a longitudinal section of an ordinary sand flask ready for the pour, and having my im roved chill in osition therein; Fig. 2 is a simi ar view after t ie cast has been made, showing a sash weight formed in the sand. Fig. 3 is a detached view of my chill, and Fig. 11 is a top plan view oi the same.

Throughout the different views shown in the drawing the numeral 1 designates an ordinary constructed sand llask which is preferably made large enough to accommodate a plurality of weights at one pouring of the metal. The necessary pattern for the Specification of Letters Patent.

Serial No. 436,785.

body portion of the weights, is withdrawn from the sand in the usual well known manner, thereby leaving the cavity 2, which is connected by a gland 3 with the transverse main passage 4, which communicates with all the weight cavities in the series, and likewise with the gate 5. After the atterri has been withdrawn from the san, my improved chill is inserted any required distance 1n the end oi the cavity 2 from which the attern was drawn; the distance said chi l is inserted determining the length ol the weight.

The chill which forms the eye end of the weight, and which I consider a great advantage and improvement over those now in use,

consists of two approximately7 similar halves- 6 and 7, which, when brought together, with their outer ends in contact with each other, as shown in Fig. 3, will form the main portion of the chill, of a bifurcated construction, and provided with a concave recess 8 for the purpose of forming a rounded head on the weight. Each of the two halves 6 and 7 has formed thereon an extension part 9 and 10 respectively, the metal atl the lower edge oi' each being hollowed out to form the seat 8 which rovides the rounded contour of the eye enc oi the weight.

As will be seen by referring to Fig. 3 the two aforesaid extension members do not meet or contact with each other, except at the extreme lower edge where they join the main portion of the two halves; a spaceof redetermined width being thus provided between said two extensions. In each of the said extension portions 9 and l0 is formed an aperture 1l, and through these openings is passed a sand core 12, which bridges the intervening space between the two extensions, and forms the third member in the completion of my chill. When assembled with the two main body members, and placed in position in the flask, a chilled eye on the weight is formed.

The inner contacting face of either one of the half portions 6 or 7, is provided with a projecting lug 13 which is desi ned to register and seat in a corresponding y formed recess 14 formed in the o posite member. This construction affords a Focking means for reventing the said two halves of the chill rom moving one against the other when seated in the flask, and overcomes the possibility of either half being moved away from its required position, thereby avoiding any bleeding when the cast is being poured.

` defect, which is a parent in the patent to Buchanan, referre to. By providing a sand core7 as heretofore described, a positive eye will result in every weight and cast, and when the casting is removed from the mold the sand core can be easily broken, and the two halves of the chill separated from the weight.

I do not claim any novelty in the flask shown, in which the weights are cast, as this feature may be entirely dis ensed with, and other means substituted t erefor; such for instance as a bed of sand provided with movable ends, or any other suitable construction.

What I claim as new, and desire to secure by Letters Patent is:

1. A three part sash weight chill consisting of two approximately similar members each being provided with an extension part, the inner faces of which are at some distance from each other when the two halves are in engagement suitable apertures being formed ythrough each of said extensions; and a sand core seated in said apertures and bridging the space between the two extension portions.

2. A three part sash weight chill consisting of two approximately similar members each being provided with an extension part, the inner faces oi' which are at some distance from each other when the two halves are in engagement; suitable apertures being formed through each of said extensions; a sand core seated in said apertures and bridging the space between the two extension portions; and means for locking the said two halves against movement one with the other when f in the sand.

3. A three part sash Weight chill consisting of two approximately similar members each being provided with an extension part, the

inner faces o'l' which are at some distance jA from each other when the two halves are in engagement; registering concaved surfaces to form the rounded outer portion of the eye; suitable apertures being formed through each of said extensions; a sand core seated in said apertures and bridging the space between the two extension portions; and means for locking the said two halves against movement one with the other when in the sand.

In testimony whereof, I aflix my signature, in presence of two witnesses.
